Hi,

 

I made an item that I want to damage the entities more if the player is sprinting (Bonus damage).

The item must deal the normal damage when the player isn't sprinting.

Which function do I best use for this?

 

Thanks!

You'll probably want to override

Item#hitEntity

to check if the player is sprinting before dealing the bonus damage.

If your item is an instance of ItemSword than you can override the hitEntity method. In here you should check if the attacker is sprinting (by using attacker.isSprinting()) and if he is then you should apply more damage by doing target.attackEntityFrom(source, amount), where source is the source of your damage, and amount is the amount of damage you want to do. An example of the code could be this

@Override
public boolean hitEntity(ItemStack stack, EntityLivingBase target, EntityLivingBase attacker) {
	if(attacker instanceof EntityPlayer) {
		EntityPlayer player = (EntityPlayer)attacker;
		if(player.isSprinting())
			target.attackEntityFrom(DamageSource.causePlayerDamage(player), this.getDamageVsEntity() * 2);
		else
			target.attackEntityFrom(DamageSource.causePlayerDamage(player), this.getDamageVsEntity());
	}
	return super.hitEntity(stack, target, attacker);
}

	}
	return super.hitEntity(stack, target, attacker);
}

 

ItemSword

's override of

Item#hitEntity

doesn't deal any damage, that's handled by

EntityPlayer#attackTargetEntityWithCurrentItem

.
